AbstractThe Quest for Seamless Geo-spatial Databases for National Water-Quality Assessments Track: Water Resources Author(s): Mauro Di Luzio This paper describes some practical aspects related to the search and implementation of seamless databases for water resources region/nation wide applications. The description refers to a specific case study, the United States Department of Agriculture Conservation Effects Assessment Project (CEAP). This project includes the use of agricultural management hydrological models to quantify the environmental benefits of conservation practices at the national scale. In CEAP, these models are part of an informational framework (CEAP-HUMUS), which is being developed and continuously enhanced, and which includes a set of customized and/or newly developed databases. Part of these databases depict fundamental landscape characteristics and are the results of merging statistic-designed survey data and ancillary data (i.e. landuse-landcover, soil, and management practices). These and the spatial time-series forcing input are being implemented using the geodatabase standard, which is also used for other developing databases and constitutes the backbone of the entire modeling framework.
